Abstract
A controller of the present invention is provided for valve to be connected thereto. The controller is used for executing rotation and movement motion so as to operate the stem of the valve and to control connection conditions of the valve. As such, the valve assembled with the controller can be controlled and switched automatically. Cost of management of factories is minimized.
Claims18
A controller for rotation and movement motion, comprising:
- a shell;
- a main axle, rotatably disposed on the shell, the main axle being rotatable about a longitudinal direction of the main axle;
- a working axle, disposed on the shell rotatably and movably, the working axle being rotatable about an axis defined by the working axle, the working axle being movable along the axis;
- a rotation means, used for intermittently turning the working axle to rotate about the axis when the main axle rotates;
- a movement means, used for moving the working axle to reciprocate along the axis when the main axle rotates;
- and
- an actuator, connected to the main axle, the actuator being adapted for turning the main axle to rotate;
- wherein the main axle is parallel to the working axle, the movement means comprises a rail column, a linkage, and an abutting member, the rail column is disposed on the main axle, the rail column achieves a rotational operation relationship with the main axle, the rail column is formed with a first track extending therearound, the first track deflects along an axial direction defined by the main axle, the linkage has a pole, a first slidable member, and a second slidable member, the pole is disposed on the shell, the linkage is pivotable about the pole with respect to the shell, the pole is perpendicular to the axial direction, the first slidable member is slidably received in the first track, the abutting member achieves an operation relationship with the working axle, the abutting member is formed with a circular second track extending around the working axle, and the second slidable member is slidably received in the second track;
- wherein the pole longitudinally extends in a direction perpendicular to the axial direction, the linkage integrally extends from the pole and terminates in a position which corresponds to a position of the first track, one end of the linkage is pivotally disposed radially around and non-displaceable relative to the pole, the first track is a groove annularly radially recessed on a circumferential outer surface of the rail column, the second track is a groove radially recessed on a circumferential outer surface of the abutting member, the first slidable member extends from the other end of the linkage and radially into the first track, the second slidable member extends from an intermediate portion of the linkage and radially into the second track, and the pole serves as a common swinging center of the first slidable member and the second slidable member.
